U.S. Environmental Protection Agency (USEPA) and the U.S. Geological Survey (USGS). 2005 1.0 vector digital data withheld NHDPlus_Flowline_100K This dataset is constructed from the NHDFlowline shapefiles from the NHDPlus data model for regions 04 and 05. The flowline features are included for the sub-basins (HUC8s) intersecting the State of Ohio. Attributes from the NHDFlowlineVAA, FlowlineAttributesFlow, FlowlineAttributesNLCD, and FlowlineAttributesTempPrecip tables (also of the NHDPlus data model) are joined to this data set. The stream order attribute field is updated with the SOSC table of the NHDPlus "Data Extensions". The stream order update is described below. The NHDPlus data model is described below. The NHDPlus is distributed with a stream order attribute (NHDFlowlineVAA.StreamOrder) that was built using an algorithm that contained a simple correction for the effect of divergences. While these stream order values were fairly reasonable for low order streams (1,2, and 3), in large rivers and braided area, the values became unpleasingly large. Several folks in the EPA laboratory in Corvalis, Oregon designed a more complex algorithm which was implemented by the NHDPlus team. The NHDPlus Version 1.0 is an integrated suite of application-ready geospatial data sets that incorporate many of the best features of the National Hydrography Dataset (NHD) and the National Elevation Dataset (NED). The NHDPlus includes a stream network (based on the 1:100,000-scale NHD), improved networking, naming, and "value-added attributes" (VAA's). NHDPlus also includes elevation-derived catchments (drainage areas) produced using a drainage enforcement technique first broadly applied in New England, and thus dubbed "The New-England Method". This technique involves "burning-in" the 1:100,000-scale NHD and when available building "walls" using the national Watershed Boundary Dataset (WBD). The resulting modified digital elevation model (HydroDEM) is used to produce hydrologic derivatives that agree with the NHD and WBD. An interdisciplinary team from the U. S. Geological Survey (USGS), U.S. Environmental Protection Agency (USEPA), and contractors, over the last two years has found this method to produce the best quality NHD catchments using an automated process. The VAAs include greatly enhanced capabilities for upstream and downstream navigation, analysis and modeling. Examples include: retrieve all flowlines (predominantly confluence-to-confluence stream segments) and catchments upstream of a given flowline using queries rather than by slower flowline-by-flowline navigation; retrieve flowlines by stream order; subset a stream level path sorted in hydrologic order for stream profile mapping, analysis and plotting; and, calculate cumulative catchment attributes using streamlined VAA hydrologic sequencing routing attributes. The VAAs include results from the use of these cumulative routing techniques, including cumulative drainage areas, precipitation, temperature, and land cover distributions. Several of these cumulative attributes are used to estimate mean annual flow and velocity as part of the VAAs. NHDPlus contains a snapshot (2005) of the 1:100,000-scale NHD that has been extensively improved. While these updates will eventually make their way back to the central NHD repository at USGS, this will not have happened prior to distribution of NHDPlus because the update process for the central NHD repository is still in development. Consequently, the NHDPlus will contain some temporary database keys and, as a result, NHDPlus users may not make updates to the NHD portions of NHDPlus with the intent of sending these updates back to the USGS. Once the NHDPlus updates have been posted to the central NHD repository, a fresh copy of the improved data can be downloaded from the central NHD repository and that copy will be usable for data maintenance. Note that the NHDPlus products are tightly integrated and user modifications to the underlying NHD can compromise this synchronization. The geospatial data sets included in NHDPlus are intended to support a variety of water-related applications. They already have been used in an application to develop estimates of mean annual streamflow and velocity for each NHD flowline in the conterminous United States. The results of these analyses are included with the NHDPlus data. A water-quality model developed by the U.S. Geological Survey (USGS) called SPARROW (Spatially Referenced Regressions on Watershed Attributes), can utilize the NHDPlus network functionality to track the downstream transport of nutrients, sediments, or other substances. NHDPlus water bodies and estimates of streamflow and velocity are used in SPARROW to identify reservoir retention and in-stream loss factors. NHDPlus climatic and land surface attributes can be used in SPARROW to identify potential factors in the delivery of nutrients from the land surface to streams. NHDPlus land cover information is useful for SPARROW in determining potential sources of nutrients. NHDPlus data is also being used in select areas for a USGS Web-based application, called StreamStats. StreamStats provides tools to interactively select any point on the NHDPlus to obtain streamflow and watershed characteristics for the selected point. NHDPlus has been designed to accommodate many users needs for future applications. NHDPlus provides the framework and tools necessary to customize the behavior of the network relationships as well as building upon the attribute database, for which the user can assign its own data to the network.
